Just so we are clear, Pedro had the same frame and power his entire career, if power/frame is your metric. So from late 80s (minors) and early 1990s through the 2000s is the potential steroid era then.
I just want to make sure that guys like Will Clark, Glen Davis, McGriff, Ricky Henderson, Gaetti, Joe Carter, Eddie Murry, Kevin Mitchell, Ryne Sandburg, Rob Deer, Andre Dawson etc. ad nauseum are all suspected steroid users. They at least need to be part of the conversation if we open up the metrics.
Also this inadvertently implies that no one is more talented than anyone else, and everyone should play virtually the same in some small narrow window.
